摘要:

A device with a low-pressure multistep avalanche chamber for thermal neutron imaging was developed and tested on a neutronographic beam of the nuclear reactor. The device operates on-line with a minicomputer. The detection efficiency of thermal neutrons is better than 3%, while the detection efficiency of 60 keV γ-quanta is less than 10−6.
